To quote: My PSGroove fork is up! Functions are relocatable and it includes the USB stick apploader payload.

Payloads

This fork comes with multiple payloads, which you can enable by editing port1_config_descriptor.S. All payloads have been rearranged so that they do not use hardcoded addresses anymore; you can rewrite and resize functions without worrying about offsetting others.

### Default Payload
The default payload performs the basic PSGroove exploit; it allows you to install and run unsigned packages.

### Apploader Payload
This payload makes use of the /app_home/PS3_GAME menu item. You may place an application on a USB drive under the PS3_GAME folder to run it without installing a package.

Note that simply extracting a .pkg onto the USB drive is not quite enough for a program to run. EBOOT.BIN must be slightly modified to boot properly.

then open up the .h file. this will create aerialx's payload. to compare to the 'default' payload included with his source for comparison, edit port1_config_descriptor.S then remake the payload with the above command.

this is all way beyond my knowledge right now and i dont see it as simple as just inserting some of the code from the default to his payload.

You're right, I just noticed that i cannot run my backups with this port, so i guess it's not compiled correctly and maybe that's why backups and the apploader don't work... btw. running it with a Teensy2.0.
